The url-pattern, /ConfirmationServlet, inside the servlet-mapping tags refer to
the servlet-name ConfirmationServlet that is defined inside
the servlet tags to be the servlet-class app.forward.ConfirmationServlet.

For those who participate in the review:
create a HTML page in Netbeans
and replace generated code for the html file with that shown above (the name of the html should be multiplevaluedataentry and places in the folder web).

Creating Deployment descriptor.

To run this Servlet you have to deploy it to a web-server or a Application
server. To deploy means to install the Servlet with some instruction
to a such server.

The instructions are mainly defined to be deployment descriptors.
The standard part of the deployment descriptor should be in an
XML-file with the name web.xml. In the later version of java it is
possible to specify this in the form of annotations in front of the Servlet.

You may need to create a Deployment descriptor file,
web.xml in Netbeans.

The contents of the web.xml file regarding servlet, SimpleServlet,
should look like this:

This file starts with the normal xml tag for a XML file and
the root tag for the deployment descriptor is web-app. Every ting
inside the last tag is to tell the server about our application,
which in this case is a Servlet.

With a servlet tag we give the Servlet class a servlet name,
which is used in the servlet-mapping tag to specify a url
for the Servlet.

In this way we can have many urls for the same servlet.

As shown above, we also need to enter the ConfirmationServlet with mapping information.

If no session-timeout (the server ends the service
of the application after this time) is given a standard timeout for the server is used
as timeout for the application.

The welcome-file tag specifies the startup for our application,
which in this case and our application is the welcome file multiplevaluedataentry.html.
Reorganize the welcome-file-list to what is shown above.

Creating Web-server Deployment descriptor.

The context-root (in example /ServletRequestforwarding) for the application
will in most cases be specified by a server vendor deployment descriptor.
